摘要

A cylinder liner (1) for an internal combustion engine is spray-coated on its cylindrical inner surface with a hard wearing layer (7), and after the spraying and a possible trueing of this hard wearing layer, the inner surface is coated with a running-in layer (8) without machining the hard wearing layer to low roughness. Between these two layers, one or more intermediate layers (9) may also be sprayed on, the hardness of which is lower than the average hardness of the wearing layer, but higher than the hardness of the running-in layer. Before contact with the piston rings, the wearing layer (7) sprayed on has in itself a roughness of at least N9 and preferably a roughness in the interval between N11 and N12. The running-in layer (8) may be of graphite balls coated with metal, such as molybdenum, aluminium, silver, or nickel, to improve lubricating conditions when the liner is run in.
